Greenies vs Crumps' Naturals vs RedBarn Dental Chews 2026: Calories, VOHC Claims and Cost per Chew by Dog Size

A customer came in last month with a 22 lb beagle mix, a vet estimate for a dental cleaning, and three chews in her hands: a bag of Greenies Petite, a pack of Crumps' Naturals sweet potato chews, and a RedBarn bully stick. Her question was blunt — "which one actually cleans teeth, and which one is just calories?" That's the right question, and the answer differs by product type. If you want a chew with published plaque-and-tartar data behind it, Greenies is the one with the Veterinary Oral Health Council (VOHC) seal; if you want a low-additive, single-ingredient chew that still gives mechanical scraping, the Canadian and rawhide-free options in our dog treats collection are the better fit.

Below, we break all three down on calories per chew, what the VOHC seal does and doesn't prove, how to work out cost per chew yourself, and which size to buy for a 10 lb, 25 lb or 60 lb dog. Everything here is educational — dental disease is a medical condition, so a chew is a maintenance tool, not a substitute for the oral exam your veterinarian performs. You can also browse dog health and wellness supplements if your vet has flagged plaque, bad breath or gum inflammation.

Greenies: the only one of the three carrying a VOHC seal

Greenies Dental Chews carry the VOHC Seal of Acceptance for plaque and tartar control in dogs, which means the manufacturer submitted controlled trial data showing a measurable reduction versus a control group. Calories run roughly 26 kcal for Teenie (5–15 lb dogs), 52 kcal for Petite (15–25 lb), 90 kcal for Regular (25–50 lb) and 139 kcal for Large (50–100 lb).

The mechanism is texture, not chemistry. The chew is extruded so it flexes around the tooth instead of shattering, letting the surface wipe the crown and reach slightly below the gumline. The guaranteed analysis on the Original recipe lists roughly 28–30% crude protein and about 5% crude fat, with the protein coming largely from wheat gluten and gelatin rather than meat — worth knowing if your dog is on a limited ingredient elimination plan. There's also no grain-free version of the Original line, so a dog on a grain-free diet for a diagnosed sensitivity may not be a candidate.

The calorie math most owners skip

Treats should stay at or below 10% of daily calories — guidance echoed by the American Veterinary Medical Association and by most veterinary nutritionists. A 10 lb dog eating around 250–275 kcal a day has a 25–27 kcal treat budget, which one Teenie chew fills entirely. A 25 lb dog at roughly 500 kcal has about 50 kcal to spend, and a Petite chew uses all of it. A 60 lb dog at roughly 1,100 kcal has around 110 kcal, so a Regular chew leaves a little room.

That's the part we spend the most time on in the store. If you're feeding a daily dental chew, you generally need to reduce the meal portion slightly or drop the other biscuits — otherwise you're adding 8–15% more calories to the day, which shows up on the scale within two months. Pet owners tell us this is the number-one reason their dog gained weight during a dental-care push.

Are Greenies safe for dogs?

Greenies are considered safe for most dogs when you feed the size band matched to the dog's weight and supervise chewing. The main documented risk is swallowing large pieces whole, which is why sizing matters more than brand loyalty. Puppies under six months and dogs under 5 lb aren't candidates.

Our team at Ashario Pets recommends breaking the chew in half for enthusiastic gulpers, taking it away when the piece is small enough to swallow, and never giving a Teenie to a 60 lb dog because it's cheaper per chew. Dogs with a history of gastrointestinal obstruction, dental fractures or missing teeth should get clearance from their vet first. Who it suits: owners who want documented plaque reduction, dogs who chew moderately, and households already brushing a few times a week and looking for a between-brushing tool.

Crumps' Naturals and RedBarn: the single-ingredient and long-chew route

Neither Crumps' Naturals nor RedBarn has submitted products for VOHC acceptance, so neither can make a validated plaque-reduction claim. What they offer instead is mechanical abrasion from prolonged chewing plus short, readable ingredient panels — the reason they dominate our chew shelf for dogs with food sensitivities.

Crumps' Naturals is a Canadian company built on dehydrated single-ingredient treats: sweet potato chews, dried liver, and similar cuts with one item on the ingredient list. Sweet potato pieces are the low-calorie end of the shelf at roughly 10–20 kcal each, with meaningful fiber content and almost no fat, which makes them a sensible pick for overweight dogs or dogs on a fat-restricted plan. Dried organ and muscle pieces run higher — often 25–35 kcal apiece — but deliver protein content well above 50% on a dry-matter basis. You'll find these throughout our dog supplies and treat aisles, and more Canadian-made options on our made in Canada pet products page.

RedBarn covers the durable end: bully sticks, Chew-A-Bulls, and filled bones designed for dogs who finish a Greenie in 40 seconds. Bully sticks are pure beef muscle, roughly 80–90% protein by dry matter, and calorie-dense — commonly estimated at 9–22 kcal per inch depending on thickness. A 6-inch standard bully stick can therefore land anywhere from about 55 kcal to over 130 kcal. That's a real number for a 15 lb dog and a rounding error for an 80 lb dog.

Why chew time matters for teeth

Abrasion is a function of contact time. A chew that lasts 30 seconds touches each tooth briefly; a bully stick that occupies a dog for 25 minutes gives sustained scraping along the carnassial and premolar surfaces where tartar accumulates first. Research indexed on NCBI/PubMed on canine periodontal disease consistently links mechanical chewing with reduced calculus accumulation, though the size of the effect varies widely by product and by dog.

The trade-off is fracture risk. Hard chews, antlers and weight-bearing bones have been associated with slab fractures of the upper fourth premolar. We steer power chewers toward collagen and bully-style chews rather than the hardest options available, and we tell customers to retire any chew once it's short enough to be swallowed. Who they suit: dogs on limited ingredient or novel-protein diets, dogs who need 15+ minutes of chewing to settle, and owners who want to know exactly what's in the chew.

What our staff recommends

In our store we see the best results from a two-chew system rather than brand loyalty: a VOHC-accepted daily chew sized correctly, plus one longer natural chew two or three times a week for contact time. That combination costs less per month than a single dental cleaning and keeps calories predictable.

Here's how we size it by dog weight:

• Under 15 lb — Teenie-size dental chew (~26 kcal) daily, plus a small dehydrated sweet potato piece (~10–15 kcal) on alternate days. Skip bully sticks thicker than a pencil.
• 15–25 lb — Petite dental chew (~52 kcal) every second day rather than daily, since one chew consumes the entire 10% treat budget. Add a thin 5-inch bully stick twice weekly.
• 25–50 lb — Regular dental chew (~90 kcal) daily is workable if you trim about 1/8 cup of kibble that day. A standard-thickness 6-inch bully stick 2–3 times a week.
• 50–100 lb — Large chew (~139 kcal) daily, plus a jumbo or braided chew weekly. Big dogs earn the calorie room, but supervise — large-breed dogs are the ones who try to swallow the last two inches.

On cost per chew, we won't quote numbers that change monthly, but the math is easy: divide the bag price by the piece count printed on the label, then divide by the days it covers. A 27-count value bag of dental chews fed daily is a 27-day supply; a 12-count bag of bully sticks fed three times a week is a four-week supply. Compare the two on cost per week, not cost per bag — and if you find a lower advertised price elsewhere, our price match guarantee applies.

When a customer comes in with a dog who already has visible brown tartar, we're honest: chews slow new plaque, they don't remove hardened calculus. That's a scaling job under anesthesia. Ask your vet, and use the chew afterward to protect the result.

We're at 1111A Finch Ave W, Unit 2, North York, ON M3J 2P7, open 7 AM to 11 PM daily, and we deliver around the GTA via Instacart and other services. Bring your dog's current food label with you and we'll calculate the treat budget with you at the counter — or contact our store first.

Questions dog owners ask about dental chews

Which dental chews are VOHC approved in Canada?

Of these three brands, only Greenies Dental Chews hold VOHC acceptance for plaque and tartar control, and that seal applies to the product wherever it's sold, including Canada. Crumps' Naturals and RedBarn chews are not VOHC-submitted. The council reviews submitted trial data rather than testing every product on the market, so absence of the seal isn't proof a chew doesn't help.

It's also worth remembering that VOHC awards separate seals for plaque and for tartar (calculus), and some products earn only one. Check the label for which claim is accepted. Treat and chew labelling in North America falls under the framework maintained by AAFCO, whose 2026 Official Publication continues to require that treats intended as snacks be identified as such rather than as complete diets.

How many calories are in a dog dental chew?

Most dental chews contain between 20 and 140 kcal each, scaling with the size band. Roughly: 26 kcal for a chew sized for a 5–15 lb dog, 52 kcal for 15–25 lb, 90 kcal for 25–50 lb, and 139 kcal for 50–100 lb dogs. Natural single-ingredient pieces range from 10 to 35 kcal, while bully sticks run 9–22 kcal per inch.

Always find the "calorie content" statement on the package — it's required alongside the guaranteed analysis, and it's the only number that lets you fit the chew into the day honestly.

What's the best dental chew for small dogs in Canada?

For dogs under 15 lb, a Teenie-size VOHC-accepted chew at about 26 kcal is the most efficient option, because it delivers documented plaque control within a tiny calorie budget. Pair it with thin dehydrated sweet potato or liver pieces at 10–15 kcal for training rewards so the total stays under 10% of daily intake.

Small breeds — Yorkies, Shih Tzus, Chihuahuas — carry the highest periodontal disease burden of any group, a pattern documented by the American Kennel Club and echoed in veterinary dentistry literature. Their teeth are crowded in a short jaw, so plaque sits undisturbed. Daily attention matters more for them than for a Lab. Bring the same discipline to their diet with a small-breed formula from our dry dog food shelf.

Can a dental chew replace brushing?

No. Brushing with a canine-specific paste remains the standard for home dental care, and chews are supplementary. A daily chew plus brushing 3–4 times a week is a realistic target for most GTA households — far better than brushing perfectly for two weeks and then quitting.

Owners walking dogs at G. Ross Lord Park in January tell us the last thing they want after a slushy walk is a toothbrush fight. Fair enough. That's exactly when a correctly sized chew earns its place. For more on building a routine, see our dog wellness needs guide.

At a glance: Greenies is the only one of these three brands carrying the VOHC seal for plaque and tartar control, with chews from ~26 kcal (Teenie) to ~139 kcal (Large). Crumps' Naturals offers Canadian single-ingredient chews at 10–35 kcal per piece for sensitive or overweight dogs, while RedBarn bully sticks provide 15–60 minutes of abrasion at 9–22 kcal per inch. Keep all chews within 10% of daily calories and size them to your dog's weight.
